lMPRovM ENT IN BRACELETS.

Specification forming part of Letters Patent No. 221,926, dated November Q, 1879; application filed `March T21, 1879.

To all whom itmay concern:

B e it known that I, ADOLPH W. MAGER- HAUS, of New York, in the State of N ew York,

have invented a new and useful Improvement in Bracelets, of which the following is aspecitication.

In bracelets made of onyx or other valuable stones, or of glass in imitation of such stones, it is very desirable to show as little as possible of the gold or other metal of which the hinges and clasps are made.

My improvement consists in the construction of the clasp andin the manner of attaching the clasp and hinge to bracelets made of the above-mentioned materials, or of such material as will not allow the attachment of said parts as hinge and clasp to the body of the bracelet by means of soldering.

In the accompanying drawings, Figure I represents a top view of a bracelet consisting of stone or glass and embodying my invention. Fig. II is a 'front view, showing the clasp. Fig. III is a back view, showing thehinge. Fig. IV is a section of the clasp in an enlarged view; and Fig.,V is a horizontal section of the same. l

Similar letters represent similar parts in all the figures.

A A represent the body of the bracelet; B, the hinge, and C the clasp. The back plates, o and w, to which the parts forming thc clasp and hinge are attached, are made circular, fitting into suitable circular cavities or recesses made in the ends of the body of the bracelet, as such cavities can easily be out or ground out of this body whatever material the bracelet may be made of. To these plates projecting pins 71, h, two to each plate, and made of a yielding or somewhat ilexible material, such as soft brass or silver, are securely fastened. The holes to receive these projecting pins are drilled or bored into the material forming the bracelet, diagonal to each other, inclining either inwardly toward each other or turning outwardly, as shown by the dotted lines in Fig. IV. These pins, as above described, being made of a softer material, it will readily be understood that the same can easily be bent to enter the holes, and by pressing the parts of the hinge or clasp further in their proper position will bend and follow the direction of the holes, and when in their places, and the back of the plates 'v and w, tting exactly the corresponding recesses made in the edges of the body of the bracelet, will be held perfectly secure Without the necessity of riveting these back plates to the body of the bracelet, as is usually done at present on any material which will not admit of the process ot soldering. In a clasp to one of these back plates, w, the cen tral part, m, of the clasp is attached, and to the other back plate, c, the corresponding parts n n, ittin g above and below this central part, m, are attached.

Into the central part, m, two bolts, a a, are fitted and acted upon by a spring, S, placed between them. The outer ends, 2 2, of these bolts are made beveling, inclining toward the back plate c, and fitting into suitable holes in the upper and lower parts, a a.

To the bolts a a projections :v are attached, working in longitudinal slots in the case m, whereby said bolts can be moved inward against the action of their spring, S, for the purpose of withdrawing the same out of the holes in the parts a a whenever the clasp or bracelet requires to be opened, while the inclined surfaces 2 2 at the ends of said bolts Y.

of overlapping of these parts upon the material of the bracelet, l obtain thereby a bracelet showing only at each joint less than oneeighth of an inch of metal forming said hinge or clasp, and different from the material of the bracelet.

What I claim as my invention, and desire to secure by Letters Patent, is
